SUMMARY
The absolute pressure at a depth of 15 meters below the surface of the sea is calculated using the formula P = ρgh, where ρ is the density of seawater (1.03 g/cm³), g is the acceleration due to gravity (10 m/s²), and h is the depth (15 m). The pressure due to the seawater column is 153.5 kPa, which, when combined with the atmospheric pressure of 101 kPa, results in a total absolute pressure of 254.5 kPa. This calculation demonstrates the relationship between depth, density, and pressure in fluid mechanics.
